+# Deploy via package-updater (composite action)
+
+Notifies `package-updater` to `docker compose pull` + `up -d` for the matching service(s) after a CI build.
+
+## Usage
+
+In a consumer repo's `.gitea/workflows/deploy.yml`:
+
+```yaml
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    needs: [build-and-push]
+    steps:
+      - uses: gitea.example.com/shcizo/package-updater/gitea-action@v1
+        with:
+          endpoint: https://updater.example.com/update
+          image: registry.example.com/${{ gitea.repository }}
+          tag: ${{ gitea.sha }}
+          token: ${{ secrets.UPDATER_TOKEN }}
+```
+
+`UPDATER_TOKEN` should be set as an organisation-level secret in Gitea so all repos share it.
+
+## Inputs
+
+| Name | Required | Default | Description |
+|---|---|---|---|
+| `endpoint` | yes | — | Full URL to `/update` |
+| `image` | yes | — | Image reference without tag |
+| `tag` | no | `""` | Tag that was just pushed (logged for audit) |
+| `token` | yes | — | Bearer token configured in package-updater |
+
+## Failure modes
+
+The step exits non-zero if `package-updater` returns HTTP 4xx or 5xx. This is intentional — the workflow surfaces the deploy failure to whoever pushed.
